A/959CS Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
The industry requires precise positioning in environments with mechanical vibration and severe thermal fluctuations. The A/959CS encoder offers absolute read stability without the need for recounting, ensuring operational continuity in heavy machinery where incremental sensors frequently fail due to electromagnetic interference or signal loss.
It uses a robust SSI interface with reverse polarity protection and a 10-30 VDC power supply. The 16-bit resolution allows for fine angular tracking, while the LED light source ensures a lifespan exceeding 100,000 hours without degradation of optical performance under normal industrial operating conditions.
Constructed with an aluminum or stainless steel housing, it withstands extreme temperatures between -40 and +85 degrees Celsius for critical applications. Its compact design integrates a spring coupling on the hollow shaft for easy, tool-free installation. Available in guemisa.es.
- SSI interface with integrated reverse polarity protection.
- LED light source with a lifespan exceeding 100,000 hours.
- Mechanical resistance to impacts of 30 G and vibration of 10 G.
- Continuous operation over a wide thermal range of -40 to +85 °C.
Technical Frequently Asked Questions
What precautions should be taken during axle installation?
Ensure angular and radial alignment according to the maximum compensation specifications (±1° ang, ±0.2 mm rad) to avoid reading errors. The built-in spring coupling facilitates connection to the motor without the need for complex external components that could introduce mechanical play in the transmission system.
What types of connectors are compatible with this model?
Radial or axial connections are offered with a 1-meter cable included, available in standard IP65 or sealed versions. Options are also available for connecting via an RS422 line driver (W code) which improves immunity to electrical noise over long transmission distances.
What are the recommended environmental operating limits?
The device operates in a temperature range of -40 to +85 °C (storage: -40 to +85 °C), although the cable output has a specific range of -5 to +70 °C (note 1). The 98% can withstand ambient humidity without becoming liquid. It is recommended to avoid direct condensation on the internal optical components to maintain SSI signal integrity.
